1. Preparations for Run 6 Don Lynch February 13, 2006

2. Completed Tasks Clean up water in dry air supply lines to BBC and MuTr Reinstall BBC Install MPC Prep and roll in EC Complete IR stainless piping and flow control for HBD Disassemble and stow TOF West installation fixtures and work platform Reconnect EC services Build shield wall Install shield wall Pink sheets and blue sheets Build lift table extenmsions Repair DC Beam in blue ring Safety Walkthru Start watch shifts

3. Completed Tasks

4. Remaining Tasks MPC test and fix MPC dry air supply manid=fold RXNP detector PMT magnet tests –Fabricate test fixture –Run tests BLM test –Fabricate fixture –Install for run –Un-install when HBD is installed Start flammable gas Start of Run party Beam in yellow ring Start recording physics New LN2 Dewar for BBC cooling gas (replacing dry air) Install HBD (~March-April prototype or ~May ½ final design)

5. RXNP PMT in magnetic field tests Photo-multiplier Tubes (PMT’s)

6. RXNP PMT in magnetic field tests

7. Beam Loss Monitor Tests 3 BLM’s 2 Chipmunks 2 stripixel detector samples 16 diodes (8 small, 8 large) 2 thermorecorder buttons

8. Beam Loss Monitor Tests Diode Holder

9. LN 2 Supply Acquire ASME NB certified 6000 gal LN 2 Dewar CA internal cryo and mechanical safety review Modify gas pad layout to accommodate dewar Install dewar on pad LN2 dewar to be located on south side of pad beyond CO2 unit shown here

10. LN 2 Storage Dewar for BBC Acme Cryogenics 6000 Gallon vessel 23’ long x 10’4” high, 7’ wide footprint 219psig MAWP, we would set MOP to 125psig. Original Mfr.: Linde, NB #6363 ser.#206 Remanufactured by Chart

11. LN 2 Supply Acquire ASME NB certified 6000 gal LN 2 Dewar CA internal cryo and mechanical safety review Modify gas pad layout to accommodate dewar Install dewar on pad LN2 dewar to be located on south side of pad beyond CO2 unit shown here

12. LN 2 Storage Dewar for BBC LN 2 Vessel to go here

13. New Gas Pad Design. Dimensions and access to be added. Estimated weight of 6000 gallon tank 30 tons when full, 10 tons when empty. Experimental safety review required. LN 2 Storage Dewar for BBC

14. HBD Prototype Mounting Prototype can not use final design mounting due to differences in location of connectors and other basic design differences. Final HBD design is not yet fixed. Prototype mounting to be fabricated from fg unistrut.

15. Shutdown 2006 We expect a short shutdown with a full plate of work June ’06: end run 5, prep for start of shutdown, prep EC for move to AH July ’06: TOF West installation, HBD installation Aug. ’06: MPC North installation, RXNP installation Sep. ’06: Detector subsystems maintenance, roll EC in, prep for run 6 Oct. ’06: Start of Run 6
